VALVE.

Specification of Letters Iatent.

Patented July 3, 1917.

Original application filed January 18, 1908, Serial No. 411,409. Divided and this application filed November T 0 all whom it may concern.

Be it known that I, l/VILLIAM A. E. HEN- R101, a citizen of the United States, and a resident of Dorchester, county of Suffolk, and Commonwealth of Massachusetts, have invented an Improvement in Valves, of which the following description, in connection with the accompanying drawings, is a specification, like characters on the drawings representing like parts.

This invention relates to valves and particularly to valves for discharging quickly the contents of large containers.

This application is a division of my application Serial No. 411,409, and the invention is especially adapted for use in connection with washing machine containers or receptacles.

In the drawings of the embodiment of my invention illustrated and described herein,

Figure 1 is a vertical section of a washing machine container comprising my invention, partly broken away;

Fig. 2, an end elevation of the receptacle, partly broken away; and

Fig. 3 a vertical section on the line 3-3 of Fig. 1.

In the use of washing and other machines where large quantities of liquid are used and it is frequently necessary to discharge the same, time is a most important factor. Where it is necessary to discharge the contents of such receptacle by means of the ordinary valve much time is required, which seriously limits the working capacity or output of the machine.

The purpose of my invention is to provide a novel valve of such construction that it will discharge quickly a container of large capacity and thereby promote the largest possible output of the machine.

Referring first to Fig. 1, I have shown a portion of the head 1 of a container of a washing machine in which rotates a goods containing drum 2. The shell 3 of the container is provided with a discharge opening 4 of suitable size. Depending from the shell 3, Figs. 1, 3, at each end of the opening 4, is a suitable valve supporting member, as an arm 5.

Surroundingthe discharge opening 4, is a flange 6, and at suitable points thereon this flange is provided with a web 7 to which 7 Serial No. 61,394.

is pivoted, as by a pin 8, the valve 9, adapted to seat upon the lower edge of the flange 6 and close thereby the opening 4. The valve may be provided with suitable packing 10.

For opening and closing this valve 9 I have provided novel means. In order to render the construction as compact as possible and thereby enable it to be operable in the limited space existing between the bottom of the container and the floor, I have provided the valve with upwardly extended sections or lever housings 11-11.

Within each of these housings is movably mounted, as by pivoting, a lever arm 12. To the lower end of each lever arm is movably secured, also herein by pivoting the same, the upper end of a hollow lever arm 13, the lower end of which is secured to a rocker shaft 14 mounted for rotation in the lower ends of the brackets 5, 5.

In order that the valve 9 may be retained properly in closed position and yet be read ily opened when desired, notwithstanding its large size, I have conceived the idea of yieldingly supporting the same and to that end have positioned within the arm 13 a plunger 15, the enlarged upper end or head 16 of which contacts with and normally supports the lower end of the arm 12.

To yieldingly retain the plunger 15 in looking relation to the lever 12 and lever 13, I have provided a coiled spring 17 which is seated against the shoulder 18 of the lever 13 and the lower face of the plunger 16. For operating the rock shaft 14 I have provided a treadle 19, Fig. 2, one end of which is weighted at 20 to assist in closing and holding in closed position the valve 9.

When the valve is closed, the lever 13 is carried a little beyond the vertical position in its engagement with the lever 12 so that the levers are locked so they cannot be readily opened by pressure of water on the valve in connection with any slight jar of the machine.

To open the valve 9 the pedal 19 is raised or the ball 20 is depressed by the foot, thus breaking the joint of the levers 12, 13, the spring 17 yielding to permit the plunger 15 to be depressed as it passes the vertical position on its way to the right, Fig. 3, permitting the valve 9 to drop on its hinges, and held in that position until the contents of container have been discharged, when upon depression of the pedal 19 by the foot it will close the valve again.

Having described one embodiment of my invention which, however, may be varied in many details without departing from the spirit of the invention and scope of the appended claim, I claim A valve having a seat to which it is movably connected, an oifset section in the valve, a lever connected with the valve at its offset section, a hollow lever connected with the first lever and carrying a plunger seated against the end of the first lever; a spring seated against the plunger and the hollow 15 lever and a rocker shaft carrying the hollow lever and a pedal on the shaft.

In testimony whereof, I have signed my name to this specification, in the presence of two subscribing witnesses.
